Active immunity involves the production of memory cells, which provide long-term protection after exposure to antigens.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Passive immunity occurs when ready-made antibodies are received, such as those in motherâs milk (IgA).
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
The tetanus vaccine is a toxoid vaccine, meaning it contains an inactivated toxin to stimulate immunity.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Passive immunity is acquired through the transfer of ready-made antibodies, such as maternal antibodies or antibody injections.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Passive immunity occurs when ready-made antibodies, such as antitoxins, are introduced into the body.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Active acquired immunity develops when the immune system produces antibodies in response to an infection.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Active immunity provides long-lasting protection because it involves the formation of memory cells.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Live-attenuated vaccines contain weakened pathogens that stimulate an immune response without causing disease.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Vaccines stimulate active immunity by prompting the immune system to create memory cells.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Vaccines work by stimulating the immune system to produce memory cells that provide long-term immunity.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Vaccination provides **active** immunity by stimulating the immune system, not passive immunity.
Ref: NCERT Class 12 Biology Chapter 7: Human Health and Disease Immunity - Acquired Immunity - Active Passive Vaccination
Passive immunity is acquired when ready-made antibodies are transferred from another source, such as maternal antibodies or antibody injections.
